It's possible, with some fun command line help, to coax the card into working status again. I had this happen to me twice with the 8 gig card that came with my D2. The first time it took me about an hour of work on my pc to get it functioning again, and then a little more time to recover the data I wanted. The second time it happened I did the exact same thing, but then just replaced the card with another 8 gig. The original card still works, but I only occasionally use it in my camera. So I imagine not being used constantly helps it live a little longer.Kirch21 said:So my phone all of the sudden stopped detecting my SD card. I tried to mount it with a cable and got nothing. I tried to format it through recovery and it gave me an error. I put it in an SD card adapter, and into my Mac's SD card slot and it doesn't even show up on my desktop. Anything I can do?
